They seem standard at first, then intimate

To Joanna the tests seemed routine, like the sort of thing she'd experience at any doctor's visit. They even checked her eyes and ears, and took swabs from her mouth. The tube they inserted to take a sample from her stomach was unpleasant, but she didn't gag even a bit.

"Do you ordinarily not have a gag reflex?" Dr. Turner asked. The question embarrassed Joanne a little so she just nodded.

"Hmm..."

"What?" Joanne asked anxiously, trying not to look at the needle the doctor had poised at her elbow for blood samples.

"Your skin appears a little resistant to puncturing. Ah, there we go," he said, just as she turned her head. The sight of her blood flowing freely into the syringe made her light-headed. "Look away, please. It's quite common for people to pass out at the sight of their own blood."

Joanne gulped and nodded, quickly complying.

"I'm afraid we'll need to take a good-sized sample for the various tests. It's possible that whatever effect, if any, the chemical will have on you won't show in the blood just yet. Still, we'll run several tests just to be sure. There, that should do it. Now, the next part is going to be a little more embarrassing."

"Embarrassing?" Joanne cautiously looked back, relieved to find the syring gone and her blood out of sight again.

"Yes, I'm going to need you to remove your clothes and take a seat," he said, gesturing with his chin toward a gynecology chair that Joanne had been studiously ignoring.

"You.... you want..."

"Need. Well, not need, but in the interest of being thorough and cautious it is recommended that we go through with this. I would like to see if the fluids might have penetrated your - other - orifices, and if so how much and to what effect."

"Oh," Joanne gulped, then sighed.

Dr. Turner rotated his chair to give her some privacy and started righting in his file as Joanne stripped off the tiny gown they'd given her, leaving her in only her lacy bra.

Feeling **** she sat on the chair, her legs going into the stirrups.

"Very good," Dr. Turner said in a way that suggested she'd been a good girl. He fastened the straps onto her legs and used the controls to maneuver her body until her private region was completely displayed to him.

"Hmm," he frowned down at her. It wasn't the effect she normally got when a man was this close to her sex and made her forget her anxiety for a moment.

"Doctor?"

"Oh. Ahem. I have a bit of a private question. Have you had intercourse, or anal sex, recently?"
